Deal Details
MCT Store US via Amazon has Monster Open Ear AC210 Waterproof Open Ear Earbuds (White) on sale for $13.99. Shipping is free with Prime or on $35+ orders.

Thanks to community member UncleRobot for finding this deal.

Features:
  • Completely open-back design for ultimate comfort
  • The Monster AC210 Bluetooth headset uses dual powerful 12mm dynamic driver units and modified PI composite beryllium diaphragms, as well as the 30mW thrust of the DAC sound card to make the sound more three-dimensional and concrete.

I love these for running and working out at the gym. They always stay on. I even sleep with one on while listening to thunderstorms on YouTube.

Haven't used my AirPods since I got these and for under 20$ it's a deal

I just bought some bone conducting headphones. Game changer. Way easier on my ear drums and doesn't cut you off from sounds around you. These Monsters are not bone conducting, just open ear.

Excuse my ignorance, but do "Open Ear" buds let outside noise in even while sound is coming out of them?

Ah, makes sense. These are probably good when you still need to pay attention to your surroundings.

I prefer to use "Open Ear" buds as well, especially for groceries shopping. I can still communicate with other people with "Open Ears" buds.

I have these and they frequenly do not pair to iphone 17 pro right away. I have to "forget this device" and repair them, or turn off/on bluetooth. I don't have that problem with Airpods, Jlabs or Baseus ones.

Monster is a no-name brand at this point. They license their name to anyone, making money off their historic reputation.

Nothing except the cables are real Monster. Everything else is just licensing the name
